Absolutely, however it’s not exactly a buff but a a redesign.
Once you force Portuguese into a reactive playstyle, in other words, once you force them into trash units, you won the game, they become the most generic bonus-less civ. Which is very common since this civ lacks any early-game bonus, this civ can be played only from a point of advantage. Horrible Design.
With that being said, Organ gun is such a great unit, both strong and solid yet counterable. Sadly the current meta doesnt allow Unique Unit strats for the most part (unless its a chaotic post imp wars), so we even lose this aspect of Portuguese.
Portuguese don’t need “early game bonus” nor squires like many have suggested here, it’s way too shallow of an approach to fix this civ. This civ has an identity crisis, it’s beyond just buffs. Besides the repetitive request for Squires is sad, a big killer to diversity.
** * All technologies (excluding advancing ages) are researched 30% faster.**
This pathetic bonus should be removed from the game, too minor to have any impact, and doesnt contribute to the formation of an identity.
They used to be masters of exploration, how about giving them:
Outposts cost no Stone
Something to actually play around, playability, something that will enrich player’s experience, cause right now the civ is the most generic one among all 39.
Another bonus can be one that will increase the viability of their awesome Unique Unit, a bonus that will help the Portuguese player, similiarly to Spanish style, building his first Castle, this however will ruin Arena games potentially.
Perhaps a bonus that will give them tiny bit of Stone for every building they destroy. This will make a 4 M@A into a Tower Rush very diverse and refreshing way to play this civ.
One thing for sure, this civ deserves more than a little tweak, its a matter of diversity and playability.
